Let me make add a comment about the TA 18. We know that Joseph delivers products that are balanced and uncolored in their presentation. This amplifier has all of the excellent performance qualities we expect from Audio Horizons products. It is subtle, detailed, natural, lively. I found the most striking quality of this amplifier to be the way it handles the frequency extremes. I am amazed by its full range performance.
In this thread we devoted hundreds of posts in which we described the qualities of the TP 2.X preamplifier. I believe this amplifier is every bit as excellent as the TP 2.X is excellent. I'm interested to see how other audiophiles receive it.
